  • ENZYMATIC PROCESS FOR SYNTHESIZING ESTOLIDES
    Publication number: 20130102041
    Abstract: This invention is a process for enzymatic synthesis of estolides through the reaction between stearic acid and methyl ricinoleate, using an immobilized lipase as the catalyst, in a solvent-free medium. This process prevents degradation of the product, reduces the formation of secondary products that generate color and odor in the lubricant, and allows recovery of the lipase and its subsequent reuse.
